To all whom it may concern:

Be it known that I, JUSTUS RIEHL, a citizen of the United States, residing in the city of Baltimore and State of Maryland, have invented certain new and useful Improvements in Logotype-Ma(- l1ines, of which the following is a specification.

This invention relates to improvements in machines for the production of printing or type characters in lines of any convenient length, the characters being formed in relief upon type bars, from an assembled line of matrices engraved -in plates, which plates are properly positioned for forming the lines of type by means manipulated by the operation of finger keys; and the primary object of this invention is the provision of a machine as specified for forming type for printing tabular work such as taritl sheets, time tables or the like.

The invention consists: first; in, the provision of a logotype machine haying a plurality of'n' atrices manually operable for movement over a casting slot inthe machine and the provision of novel means including a'finger keyboard and a plurality of slidable pins operable'by said finger keys, for controlling the positioning of the matrices over the casting slot for forming the desired characters upon the type bars: second; in the production of a novel form of locking means for holding .the matrices firmly in position over the casting slot, which locking means is automatically operated for releasing the matrices and ejecting the type bars after the latter are cast: third; the mechanism for repositioning the slidable finger key operated pins: fourth; in the melting pot, pumps for forcing the molten metal through the casting slot, and the cam mechanism for tilting the melting pot for breaking the connection between the metal therein and the bar of type after the latter has been formed: fifth; in the mechanism for operating the various parts of the machine at the proper time to insure the proper performing of its functions: sixth ;'in a mechanism for automatically redistributirigor repositioning the matricesafter the line of I type hasbeen formed: seventh; the springs and the springspools' for moving the matthe machine.

such novel features of construction, combination and arrangement of parts as will hereinafter appear. I

In describing the invention m detail ,reference will be had to the accompanying drawin s wherein like characters designate like an corresponding parts throughout the several views, and in which:

rotation upon the shaft while the other is keyed thereupon, as is usual in the construction of pulleys for transmitting power to the propelling shafts of machinery. The shaft 5 has a gear 8 mounted thereupon, which gear meshes with a pinion 9 mounted upcn the shaft 10. The shaft 10 is rotatably supported by the frame 1, and it has an intermittent gear 11 mounted thereupon, which gear meshes with a second intermittent gear 12. The intermittent gear 12- is mounted upon the shaft 13, which shaft has sprockets 14 and 15 mountedthereupon. The sprockets 14 and 15 are of a novel form of construction, having elongated straight sides from which the teeth 16 thereof project from the communicating corners of the straight sides as is clearly shown in. Figs. 1 and .4 of the drawings.

A chain 17 passes about the sprocket wheels 14 and 15 and about sprocket wheels 18, which are arranged upon the opposite end of the supporting struc- -ture 1 of the sprockets 14 and 15, and are positioned in direct alinement with the sprockets 14 and 15. The sprocket'chain 17 has a plurality of plates 20 carried thereby, the function of,which will be hereinafter more fully described. The gear 8 has a clutch cone 25 formed upon one side thereof, which clutch cone is adapted for insertion into the clutch shell 26, which is slidably 'ounted upon the shaft 5, and has an annula; recess 27 formed therein, which recess receives the end of the forked clutch actuating lever 28. The clutch actuating lever28 is connected to a rod 29, which rod is in turn connected to a rod or bar 30, through the medium of a crank arm 31. The rod or bar 30 -is positioned near the'lower end of the supporting frame 1. of the logotype machine, and has a treadle 32 mounted thereupon for the actuation of the rod for moving the clutch shell 26 into or out of frictional peripheral engagement with the clutch cone 25 for imparting rotation to the clutch cone and the gear 8 which is carried thereby for operating the sprockets 14 and 15 and the sprocket chain 17 which is carried thereby.

Mechanism for properly positioning the slidable matrices over the casting sZ0t.The sprocket chain 17 has plates 40 secured thereto at spaced intervals along its length, which'plates are provided with a plurality of serially arranged openings 41, in which --openings are slidably seated pins 42. The

pins 42 are slidably seatedin the openings Y 41 in the plates 40, and extend thercthrough into the plates 20, which plates are posi- The plungers 52 are The supporting frame 1 of the logotype machine has a keyboard supporting casing 44 supported thereby, which keyboard casing has a removable cover 45 mounted upon its upper end, and a shaft 46 extending transversely thereacross, which shaft is 'journaled in bearings 47 and 48 mounted within the casing 44. The shaft 46 has pivotally mounted thereupon a plurality of arms 49, which arms are formed upon collars 50, within which collars the shaft 46 is seated. The collars 50 have arms 51 formed thereupon and extending therefrom from'the opposite sides of the collars to which the arms 49 are attached. The arms 51 radiate inwardly toward the center of the casin 44 and have plungers 52 formed upon t eir free terminal ends, which plungers are arranged in alinement one with the other, as is clearly shown in Fig. 10 of the drawings. provided for slidable movement within openings which are formed in the plate 45, so that when the arms 49 are forced downwardly by pressure being applied to the finger keys 53, the arms 51 will be forced upwardly and the plungers operated in the openings in the plate 45 will engagethe lower end of the pins 42, forcing them upwardly and causing them to project above the upper surfaces of the plates 20, where they will be held by the action of the sinuous resilient wires 43.

The arms 49 are limited in their downward movement by angle bars 54, which are positioned beneath the terminal ends of the arms, while the arms 51 are limited by the.

angle plate 55, which is secured to the base a of the casing 44 and [extends longitudinally therein so as to provide an abutting base for the terminal ends of each of the arms 51.

Flat springs 56 are secured to the base of the casing 44, andthey en'gag'e' 'the under surfaces of the levers 49 for repositioning them after they have been actuated by the' operation of the finger keys 53. Each of the arms 49 have two finger keys 53 secured thereto, one of which finger keys bears nudesignations. The two keys .are'provided merical designations and the other character p facilitate the depressing of the proper key.

' The finger keys 53 each bear different. des ignatlngcharacters such as numerals,reoin-' mas, periods, and various other characters such as are necessary for the setting up of. type for rinting purposes, so that when the various nger keys are operated the pin 42 carried by the plate 20 which corresponds with the characters upon the finger keys will be moved upwardly within the openings formed in the plates 40 and 20, and project above the upper surface of the plate. The sprocket 14 has an elongated hub formed upon one side thereof, which hub has a multiple ratchet 61 keyed thereupon, as is clearly shown in Fig. 9 of the drawings. The supporting structure 1 of the logotype machine has 1t bracket 62 suspended therefrom, to

which bracket is pivotall y connected a lever (33. The lever 63 has a pawl 64 mounted upon one end thereof, which pawl engages the peripheral teeth 65 of the rat het (31, for rotating the ratchet for moving the 21;? ochr-t 1? forward one space, for regmlating the dis t-ance between the letters to be formed upon the type bar. The lever 63 has a linger hey 66 attached to its end opposite to the pawl 64, which key forms the shift key for shift ing the sprocket 14 and the plates 46 and '20 carried thereby the necessary distance for providing the required amount of space be tween each number or character to be formed upon the type bar. A plurality of matrices 70 are slidably mounted in a matrix porting frame 71, and they have lugs .2 mounted upon their rear ends. which h s have coil-springs 73 secured thewto. "l as coil-springs 73 are Wound about a spring retaining spool 74, so that they will tend to force the matrices outwardly, in the fliiiec tion indicated by the arrow a in Fig, 6 of the drawings. The s 'irings are secured to pins 73, which extend through the flanges 73 of the spring retaining spool 74 and they are coiled about the core of the spool similar to the coiling of a clock spring. The free end of the springs 7 3 extend rearward and are connected to the rear ends of the ill. as is clearly shown in Fig. 16 of the ings, so that they will force the matrices outwardly upon the release of til-5 tension of the springs 73. ".lhe ring retaining spools 7e are rotatably mounted upon a shaft 75, which shaft is supported by suitable bearings 76, for rotation of the shaft for regulating the tension of the springs The shaft 75 is normally held against rotary movement by any suitable means.

The supporting frame 1 has standards 77 and 78 secured thereto, which standards have an angled lever 79 pivotally mounted upon a shaft 80, which is journalcd in their upper terminal ends. The angled lover (a hasits arms 81 and 82 disposed suhstantiall at right angles to each other, and the arm 81 has a hand grip 8?) formed thereon, while the arm 82 has its terminal end bifurcated as is showhat 84, which bifurcated and re wives a roller 85 therein. The roller 85 is carried by the matrix supporting frame 71, so that when the lever '79 is operated the matrix bars will be shoved forward by the springs 73 until the roller 85 reaches the terminus of the bifurcated portion of the arm 82, when the matrice bars will be forced far-- ther forwardly by the action of the levers. The matrix bar supporting frame 71 has a pair-'- of plates 88 secured thereto, which plates have transversely extending pins 89 formed upon their sides. The pins 89 are seated between the arms 90 and 91 Which are formed by the bifurcating of one end of a lever 92. The lever 92 is mounted upon a shalt 9 which shaft has a segmental cam mounted thereupon, which cam engages at prrdetcrmiucd times the under surface of the nnurir; baisupporting frame 71, for clexatln the forward end of the matrices for perm 11g of their free sliding movement over the: various parts of the machine positioncd in their path of travel. \Vhen the main are in their rearward position, preparatory to positioning for the forming of a typo oar, or as is shown in Fig. 6 of the running, the le\ er J55 is positioned so that the segmental cam ill will be in engagement with the under surface of the matrix supptu'ting frame 71, elevating the same, or holding the forward end of the matrices in an ele ated position with respect to the rear end thereof, and when the matrices are aimed forward the pins 89 will travel be ineeu the arms 90 and 91, for a limited distunrc, ai'tcr which the lever 92 will be actuutcd or moved forwardly, which will mo e the gmental cam 94 out of cngagcunent with the under surface of the matrix bar :mpymrling frame 71, permitting the matrices to fall downwardly and into a h0llZOI'l tal position is shown in Fig. 7 of the drawings, at which times the y are positioned over the casting slots 95, and are positioned pzu-ntory to the forming of a line of type.

The matrix bar supporting frame 71 has a inching wedge 96 carried thereby and positi ned near the rear end of the matrices, which locking wedge moves under a roller 7, which roller is supported by suitable supporting brackets 98 which are attached to the supporting frame 1 in any suitable manner.

\Vhen it is desired to form a line of type, the various finger keys are operated for projecting the respective pins 42 upwardly through the plates 40 and 20. For instance, when it is desired to make type for printing the numeral 273, the finger key 53 l if) corresponding thereto, after which the shift key 66 is again operated, and so on in succession, until the desired number of keys has been operated. After the pins 42 have been moved 1l] )\\fl1'dly so that their upper ends project out of the plate 20, the foot treadle 32 is operated, which operates the clutch shell 26, causing it to engage in the clutch cone 25, which imparts rotation to the shaft 10 and to the shaft 13 through the meshing of the intermittent gears 11 and 12, and moves the plate 520 forwardly to a position in alinement with the matrices 70. When the plate 20 is in alinement with the matrices, movement of the sprocket chain 17 and the plates 20 and 10 will be stopped, owing to the spaces which are formed upon the intermittent gears 11 and 12 as is clearly shown in Fig. 15. After the plates have been properly positioned in alinement With the matrices, the lever 79 is actuated for moving the matrices fo wardly in their supporting or carrying frame 71. The matrices move forward until they engage the respective pins 12 which have been pushed upwardly for projection above the upper surface of the plate 20, which pins stop the sliding movement of the matrices and position them over the casting slot 95, so that the designating characters which are engraved in the matrices and which correspond with the designating characters upon the finger keys which have been operated, will be properly positioned over the casting slot for the forming of the line of type, after which the mechanism for operating the melting pot and forming the type bar is operated.

The supporting structure 1 has a plate secured thereto and positioned so that the inner face of the plates 40 will engage the same, after the plates have passed about the sprockets 14 and 15 and are on their return to position above the keyboard, forthe operation of the pins 12 carried thereby. A roller 101 is mounted upon a stub shaft 102, and is positioned in alinement with the plate 100. The roller 101 has a cushioning cover 103 mounted upon its periphery, which cushioning cover engages the pins 12 upon the movement of the sprocket chain 17 and the plate 20, and forces the pins inwardly into the openings formed in the plates 20 and 10, and repositions them for reactuation by the lugs 52 which are operated by the finger keys 53.

Melting pot (UL/Z actuating mechanism tIIGTZfOIK ThG shaft 5 has a bevel gear 105 mounted thereupon, which bevel gear has a clutch cone 106 formed upon one face thereof. The shaft 5 also has a clutch sleeve or shell 107 feathered thereupon. for the reception of the clutch cone 106, by means of which the bevel gear 105 is rotated when desired. The clutch shell 107 is actuated by a lever 108, which lever is pivoted intermediate its ends at 109 to a bracket 110, and is positioned above the upper surface of the supporting frame for convenient access thereto. A shalt 111, which is supper d by suitable bearing brackets 112 and 11-"5 is mounted at right angles to the shaft 5, and it hasa bevel gear 114 mounted thereon, which gear meshes with the bevel gear 105, for imparting rotation to the shaft 111. A channel cam 115 is mounted upon the shaft 111, and has a facial channel 116 formed therein. The channel 110 has a roller 11,? rotatably mounted therein, which roller is carried by a lever 118. The lever 118 is -pivotally connected in any suitable manner to the melting pot 180, so that upon the retation of the shalt 111, the roller 11? will travel about within the channel 110 and operate the lever 118 for tilting the inelijin' pot 120 when the roller reaches the pan of the channel l'urthcrlnost from the tralrotating axis of the channel rain The melting pot 1520 is pivotally suppirrnai by bracing arms 121 and 122, which arias aresecured to the supporting frame 1 in any suitable manner.

The melting pot 120 has a. Bunsen burner 12 1 positioned in the low e1. portion thereof, for heating the type-metal which is planed in the retainingenp or part of the melt The retaining portion of the ing pot. melting pot 120 has a pump mechanism 1:52 mounted therein, which pump mechanism has an egress pipelifil fornucd thereon, which pipe extends outwardly and conununirmics with the casting slot 95. The casing of the pump 122 has an ingress opening 124-formed therein, and a piston 125 slidahly soared in the body portion of the pump and has a piston rod 126 connected thereto and pro jecting upwardly out of the melting pot 1520. The piston rod 120 is pivotally connected to a lever 12?, which lever is in turn connerted to a second lever 128, at 152.), or intermraliate its ends, as is clearly shown in Fig. .3 of the drawings.

The lever 128 is positioned vertically and is slidable through an opening 1 which is formed in a portion of the rug ,1 Q structure 1. The lever 198 has a roller 1 secured thereto and projecting trans-W1: w therefrom, which roller has periph ral gagenu'ent with a spiral cam 132'. The spiral cam 132 is mounted upon the termina? ,eud. of the shaft 111, and during the rotation f the shaft 111, the roller 131 will travel s out the periphery of the various spiral portion of the cam 13?, and operate the lcxrr 13 in a vertical up and down movement. whirl: will oscillate the lever 127 for o l'ltl-"ilil; the

piston rod 120.

The operation of the piston rod if"? w ll move the piston 11 .5 vertically within iru: 2%

pump casing, and upon its upward stroke will create a suction through the ingress opening 124, which will draw the molten metal into the pump casing, and on the downward movement of the piston 12'), the metal will be forced upwardly out through the egressing pipe 123, and through the casting slot 95, and into engagement with the matrices which are positioned over the casting slot, and thus a bar of type is formed. The cams 115 and 132 are mounted upon the shaft 111 in respective relation to each other,

so that immediately after the cam 132 has operated the piston rod 126 for forcing a charge of molten metal upwardly and out through the casting slot for forming a bar of type, the ram 115 will be positioned for tilting the melting pot 120, which will sever any connection between the bar of type and the metal which is retained within the egrtessing pipe 123, to permit of the ejection 0 he bar of type by a cam 133 and suitable mechanism 133', which cam is mounted upon the shaft 10 and moves upwardly, striking the metal bar of type immediately after the same has been cast. a

The supporting structure 1 of the logotype machine has protective casings 140 mounted thereon, which casings extend upwardly and over the sprockets 14, 15 and 18, as .is clearly shown in Figs. 1 and 2 of the drawings.

Operation.--The operator of the machine willuse the keyboard mechanism, and by tapping the keys 53 which bear the desired numbers, drive the corresponding pins 42 upwardly in the plates 20. 'Then by shifting the key 66 the plate 29 will be moved forward by means of the multiple ratchet 61 which is keyedabout the hub of the sprocket.14. The shifting of the multiple ratchet wheel 61 will move the sprocket I movement.

chains 17 forward one space, and by -repeating the operation of alternately operating the finger keys 53 and the spacing key 66, the desired line of figures is set up. After the desired number of pins 42 for reg ulating the numbers of characters to be formed on the line of type have been moved of the plates 20, the treadlc upwardly out which will force 32 is pressed downwardly,

the clutch shell 26 into engagement with the clutch cone 2:, and rotate the gear 8 and the shaft 10 through the meshing engagement of the gears 8 and 9, which will in turn rotate the intermittent gears 11 and 12, and move the sprocket chain 17 forwardly until the plate 20 is positioned in alinement with the matrices, and the casting, slot 95. The lever 79 is then moved forward and the matrices 70 are positioned over thecasting slot 95, the characters engraved therein being regulated in their positioning by the -upstanding pins 42. Upon the forward movement of the matrices 70, the locking wedge 96 will move under the r ller 97 and firmly lock the matrices in proper position. After the matrices 'are properly locked in their respective positions, the lever 108 is actuated, which moves the clutch shell 10? into engagement with the clutch cone 106, and operates the shai't 111, which imparts rotation to the spiral cam 132 and operates 'the pumping mechanism 122 which is positioned in the melting pot 120 and forces a charge of the molten metal upwardly through the casting slot 95 and into engagement with the matrices, forming a line of type. Immediately after the charge of molten metal has been forced upwardly through the casting slot, the channel ram 115 will tilt the melting pot and break the connection between the type bar and the metal which is retained in the egressing pipe of the pumping mechanism. By throwing-the levers 108 and 79 back into their normaLpositmn, the matrices will be replaced ready for the next operation. \Vhen castingthe next line of type, the moving of the foot treadle 32 will operate the cam 132 and-eject the cast type bar without extra movement of the shaft 10, or the cam 132 carried thereby. 'During the travel of the sprocket chain, the plates 20 -will be brought into contact with the plate 100 and the periphery of the roller 101.,
